2013-12-10Release LevelDB 1.15dgrogan@chromium.org
- switched from mmap based writing to simpler stdio based writing. Has a minor impact (0.5 microseconds) on microbenchmarks for asynchronous writes. Synchronous writes speed up from 30ms to 10ms on linux/ext4. Should be much more reliable on diverse platforms. - compaction errors now immediately put the database into a read-only mode (until it is re-opened). As a downside, a disk going out of space and then space being created will require a re-open to recover from, whereas previously that would happen automatically. On the plus side, many corruption possibilities go away. - force the DB to enter an error-state so that all future writes fail when a synchronous log write succeeds but the sync fails. - repair now regenerates sstables that exhibit problems - fix issue 218 - Use native memory barriers on OSX - fix issue 212 - QNX build is broken - fix build on iOS with xcode 5 - make tests compile and pass on windows git-svn-id: http://leveldb.googlecode.com/svn/trunk@78 62dab493-f737-651d-591e-8d6aee1b9529

2011-11-30Makefile fixes for systems with $CXX other than g++.hans@chromium.org
- Makefile: Use $(CXX) for compiling C++ files, don't override the environment's value of $CXX - build_detect_platform: use $CXX instead of g++. Based on bug report from Theo Schlossnagle: http://code.google.com/p/leveldb/issues/detail?id=46 (Sync with uptream at 25807040.) git-svn-id: http://leveldb.googlecode.com/svn/trunk@56 62dab493-f737-651d-591e-8d6aee1b9529
2011-11-14Pass system's CFLAGS, remove exit time destructor, sstable bug fix.hans@chromium.org
- Pass system's values of CFLAGS,LDFLAGS. Don't override OPT if it's already set. Original patch by Alessio Treglia <alessio@debian.org>: http://code.google.com/p/leveldb/issues/detail?id=27#c6 - Remove 1 exit time destructor from leveldb. See http://crbug.com/101600 - Fix problem where sstable building code would pass an internal key to the user comparator. (Sync with uptream at 25436817.) git-svn-id: http://leveldb.googlecode.com/svn/trunk@55 62dab493-f737-651d-591e-8d6aee1b9529
2011-10-31A number of fixes:hans@chromium.org
- Replace raw slice comparison with a call to user comparator. Added test for custom comparators. - Fix end of namespace comments. - Fixed bug in picking inputs for a level-0 compaction. When finding overlapping files, the covered range may expand as files are added to the input set. We now correctly expand the range when this happens instead of continuing to use the old range. For example, suppose L0 contains files with the following ranges: F1: a .. d F2: c .. g F3: f .. j and the initial compaction target is F3. We used to search for range f..j which yielded {F2,F3}. However we now expand the range as soon as another file is added. In this case, when F2 is added, we expand the range to c..j and restart the search. That picks up file F1 as well. This change fixes a bug related to deleted keys showing up incorrectly after a compaction as described in Issue 44. (Sync with upstream @25072954) git-svn-id: http://leveldb.googlecode.com/svn/trunk@54 62dab493-f737-651d-591e-8d6aee1b9529
2011-10-05A number of bugfixes:gabor@google.com
- Added DB::CompactRange() method. Changed manual compaction code so it breaks up compactions of big ranges into smaller compactions. Changed the code that pushes the output of memtable compactions to higher levels to obey the grandparent constraint: i.e., we must never have a single file in level L that overlaps too much data in level L+1 (to avoid very expensive L-1 compactions). Added code to pretty-print internal keys. - Fixed bug where we would not detect overlap with files in level-0 because we were incorrectly using binary search on an array of files with overlapping ranges. Added "leveldb.sstables" property that can be used to dump all of the sstables and ranges that make up the db state. - Removing post_write_snapshot support. Email to leveldb mailing list brought up no users, just confusion from one person about what it meant. - Fixing static_cast char to unsigned on BIG_ENDIAN platforms. Fixes Issue 35 and Issue 36. - Comment clarification to address leveldb Issue 37. - Change license in posix_logger.h to match other files. - A build problem where uint32 was used instead of uint32_t. Sync with upstream @24408625 git-svn-id: http://leveldb.googlecode.com/svn/trunk@53 62dab493-f737-651d-591e-8d6aee1b9529

2011-09-01Bugfixes: for Get(), don't hold mutex while writing log.gabor@google.com
- Fix bug in Get: when it triggers a compaction, it could sometimes mark the compaction with the wrong level (if there was a gap in the set of levels examined for the Get). - Do not hold mutex while writing to the log file or to the MANIFEST file. Added a new benchmark that runs a writer thread concurrently with reader threads. Percentiles ------------------------------ micros/op: avg median 99 99.9 99.99 99.999 max ------------------------------------------------------ before: 42 38 110 225 32000 42000 48000 after: 24 20 55 65 130 1100 7000 - Fixed race in optimized Get.

2011-08-22Bugfix for issue 33; reduce lock contention in Get(), parallel benchmarks.gabor@google.com
- Fix for issue 33 (non-null-terminated result from leveldb_property_value()) - Support for running multiple instances of a benchmark in parallel. - Reduce lock contention on Get(): (1) Do not hold the lock while searching memtables. (2) Shard block and table caches 16-ways. Benchmark for evaluating this change: $ db_bench --benchmarks=fillseq1,readrandom --threads=$n (fillseq1 is a small hack to make sure fillseq runs once regardless of number of threads specified on the command line). git-svn-id: http://leveldb.googlecode.com/svn/trunk@49 62dab493-f737-651d-591e-8d6aee1b9529
